SPECIFICATION forming part of Letters Patent No. 463,286, dated November 17, 1891.. Application filed April 30, 1891. Serial No. 391,107. (No model.)

T0 at whom itmay concern:

Be it known that I, WILLIAM EDUMN Corn, a citizen of the United States, residing at M emphis, in the county of Scotland and State of Missouri, have invented a new and useful Float-Valve, of whichthe following-is a specification.

My invention relates to an improvement in float-valves that are especially designed for regulating the supply of water from a suitable tank to a watering-trough, and has for its object to provide a valve that will effectively out off and let on a supply of water as the supply'in the tank may require, but at a small expenditure ofrpower from the float op erating the valve; and it consists in certain features of construction hereinafter apparent, and particularly pointed out in the claim.

In the accompanying drawings, Figure 1 is a perspective view of a watering-trough provided with a float-valve constructed in accordance with my invention and in the act of supplying said trough with water. Fig. 2 is a longitudinal sectional view of my valve attachment, the valve being closed and the operating-lever in ahorizontal position. Fig. 3 is a detail perspective view of the valve attachment detached from the supply-pipe.

A designates a watering-trough of the usual construction and provided with a supply-pipe B. situated near its upper edge and connected with any suitable water-supply tank, pond, or other reservoir, and is provided with my improved fioat-valve. The float-valve consists of an interiorly-threaded valve -body I), which is adapted to screw on the water-supply pipe and carry the various parts of the valve. The same is provided on its upper edge with an extension or perforated ear cl, project ing beyond the front or discharge end of the valve-body and takin g between a pair of bearing-lugs d, formed on the upper side of the flap-valve E and pivoted thereto by a pint-1e C1 The flap-valve E is adapted to bear against the valve-seat, which is the front or discharge end of the valve-body, or released from the same, according to the amount of water within the tank, and is itself provided on its bearingface with the usual elastic packing e, which is secured to the same by means of a screw a passing centrally therethrough into the flapvalve, thus providing a secure and firm attachment of the packing to the said valve and easy means for removing and replacing a new packing when the old one is worn out. The front of the flap-valve is provided with a camfaced lug e gradually enlarging toward its base or lower end, and upon the same is pivoted the rectangular link 6 Extending out in a horizontal plane from either side of the valve-stem are the inwardly-curved arms F, terminating in front of the valve in opposite perforated ears f and forming a yoke, and between the ears, by a pintle f, is pivoted the operating-lever G, which is provided at its outer end with the ordinary float H, that operates the same, according to the rise and fall of the water in the trough, and has its opposite or inner end projecting within the yoke formed by the arms F, curved upward, asshown at g, toform the outer concaved face 9' and the inner convex face 9 such curved end engaging with the link a as the Water -line lowers in the tank and the float and outer end of the rod rides loosely up through the link 6 withdrawing its convened surface from the cam-faced lug e of theflap-valve so that the pressure of water against the innerside of the valve causes the same to swingoutwardly from its seat. The water now flows into the tank, elevating the float as the Water-mark is reached until said float,.elevating the outer end of the rod G, depresses the inner end of the rod, the convex face of which now begins to ride down the cam-faced lug, and by the time it reaches the lower large end of the lug the valve is closed upon its seat, in which position it is securely held by the buoyant tendency of the float.

The operation of my valve is thought to be apparent from the foregoing description, the valve being operated either to cut off and let on the supply of water by the pivoted floatlever, and is so arranged in conjunction with the bearing-lug on the valve and the link thereon as to assume a horizontal position in closing the valve and obtain a strong leverage, with but a limited movement of the float upon the operating-lever.

Having thus described my invention, whatI claim, and desire to secure by Letters Patent, 1s

The combination, with the interiorly-threaded valve-body provided upon its upper side with a perforated ear and terminating at its outer end in a valve-seat, and the horizontally-disposed arms projecting outwardly from the sides and in front of the seat and terminating in bearing ends, of the valve hinged loosely to the bearing-ear of the body and adapted to lightly close upon the seat thereof and having its outer face provided with the cam-faced lug enlarging toward its lower end, the link extending outwardly from the lug, the rod pivoted between its ends between the bearing ends of the arms, the inner end of the rod being upwardly curved, engaging the link and provided with an inner convex bearing-face for operating against the carn-1ug of the valve, and the float connected to the outer end of the rod.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two Witnesses.
